dpkg tries to remove a config file twice ...

[Othmar Pasteka <pasteka@kabsi.at>]

hi,

i generate a config file in my postinst, hence it's not marked as
a conffile. so if the package is purged i have to remove it by
hand in the postinst:
# purge the config file which is created in the postinst script
if [ "$1" = purge ] ; then
        rm /etc/modlogan/modlogan.conf
fi

ok, i've done this. when i now --purge it i get the following:
rm: cannot remove `/etc/modlogan/modlogan.conf': No such file or
directory

after a look at the strace output it tries to remove it twice,
but can't really say why, maybe i overlooked something.
is there something i don't know but which must be in one of the
install/remove scripts?

thanks
Othmar
